What are the building
blocks from which all
parts of the human body
are formed?

Cari is looking for
what?
Cheek cell
This picture shows several
epithelial tissue cells from a
human cheek. The cell walls and
nuclei are clearly visible. The cells
are suspended in a fluid matrix of
saliva.
This picture, taken at a higher
magnification, shows the same cells
stained with methylene blue solution
to show clearly the nuclei and cell
walls. The cell in the middle which
appears to have two nuclei is most
likely two transparent cells stacked
on top of each other.
What are the structures of the cell?
1.
2.
1. Cell membrane
2. nuclear
envelope
4. Endoplasmic
Reticulum
5. Golgi body
6. Golgi body
7. Centriole
8. Lysosome
9. Mitochondrion
10. Vessicles
11. Chromatin
12. Nucleolus
13. Nucleus
19. "Dots in ER,
Ribosomes"
Cell structures and function
What are the names of the organelle structures?
Cell membrane Outside boundary of the cell
centrosome
Contains centrioles
chromatin
Loosely coiled fibers containing protein & DNA in nucleus
Cilia
Movement
Cytoplasm
Occupies space between cell membrane and nucleus
ER
Protein synthesis in RER, lipid and cholesterol synthesis in SER
Golgi body
Packaging and secretion (UPS guy)
Iysosome
Contains digestive enzyme ( garbage man of the cell)
Mitochondrion
Location of energy release from food molecules (powerhouse)
Nuclear
envelope
Separates nuclear contents from the cytoplasm
Nucleolus
Nucleus
Ribosome
Dense body of RNA within nucleus
Contains chromatin and nucleolus
Small RNA-containing particles for the synthesis of proteins
